Identification of modified natural porphyrin isomers: 1H and 13C NMR assignments by NOESY and reverse heteronuclear shift correlation

Arnaud Bondon, Marie Autret, Gérard Simonneaux

Open publisher page 8 citations

Abstract

Abstract The efficiency of two‐dimensional homonuclear 1H1H NOE spectroscopy in characterizing and fully assigning the 1H NMR spectra of several isomers of meso‐ or ring‐substituted deuteroporphyrins is demonstrated. The carbon resonances of the skeleton and the substituents were fully assigned using two‐dimensional reverse heteronuclear shift correlation spectroscopy.
